As per our Firefox Portable ESR schedule, the Firefox Portable ESR channel will be moving up to 60.x tomorrow evening. The Legacy 52 release above is for users who wish to continue testing or using the legacy version of the ESR channel. This Legacy 52 release will be maintained with any security releases made by Mozilla through September 5 according to their standard Firefox ESR release schedule. Keep in mind that this is the last version of Firefox to support legacy extensions. Any users wishing to continue using it should copy their Data directory from FirefoxPortableESR to this new FirefoxPortableLegacy52 branchy. Please note that once your copy of Firefox ESR is upgraded to 60.x, some files will no longer be compatible with the 52.x branch. You can always sync your critical data via Firefox Sync.

Sometimes, the impossible can become possible, if you're awesome!

was very glad to see the Legacy 52 edition being made available here, and installed it few days ago, just before mozilla gave up on v52esr completely and move fully to quantum.

copied the old v52esr DATA folder over to LEGACY as suggested by you, and it worked perfectly well: all history was there, all passwords, all fold-down entries in the address bar, all bookmarks.

worked with it for hours, totally happy.

closed it down, and reopened it only 30 minutes later: initially looked fine, but found out all history, bookmarks, etc etc gone, no entries at all.

thought it was just a quirk, and re-did the whole procedure again: installed a fresh copy of LEGACY, copied the older data folder over, and back it was: everything was there. happy ...

evening, computer off. next morning, same problem: history and all others gone.

tried it several times over, with PA on HDD, on USB stick, on different op systems (WIN 7/32 7/64 10/64), same problem.

if i make new additions in the adress bar, they show up in history - but only for a few hours, then they are gone too.

could it be that something was changed in the about:config settings, that overrules the normal ''NO UPDATES, HISTORY forever'' settings?

anyone else using LEGACY52 and having similar problems? has it to do with this specific portable version, or would it be the same with the installed 52esr version (which i will try on sunday?).

any idea, any suggestion where to look?

greetings - heinz -

You could try a fresh install and Firefox Sync. That would ensure everything is copacetic.

Note that this is a news story and not the appropriate place for support questions. Note also that legacy 52 is insecure and completely unsupported.

yes, sync might be an option. just thought someone else here has seen similar things. it is just sad to see things go away that have worked perfectly for years. guess we have to live with it.

it just happened again: perfect last night, empty this morning.

still investigating. so far the installed version (diificult to install and blocking updates before it auto-updates) is holding history, but so far means nothing - can happen any moment.

theory (but not only mine): could it be that MOZILLA tries to update any 52.9 version at irregular intervals, even when UPDATE is blocked? and when it doesnt succeed, it makes it unusable by erasing history, bookmarks and whatever? thats what it in effect looks like.

or is it a hidden timer-like setting in about-config?

apologies from my side, but your detailed article above was very heads-up, and the only real reference i found in the forum on LEGACY. would you want me to re-post part of it in the support section? i am sure i am not the only one coming up with this problem.

many greetings, and a nice weekend - heinz -

The Spybot search destroy program says that at me in the Local Settings\Temp\nsh7.tmp PUPS Zango folder. I opened this folder, and there several files, including the file splash.jpg, FindProcDLL.dll, newadvsplash.dll, registry.dll, system.dll. I looked at the splash.jpg file, and it is a logo of the Firefox ESR Portable program.
